CONVERTIBLE ANCHOR AND FREIGHT HOISTlNG APPARATUS FOR VESSELS.

SPECIFICATION forming part of Letters Patent No. 356,738, dated January 25, 1887.

Application filed October 16, 1886. Serial No.216A10. {N modeLl To all whom it may concern:

Be it known that I, THOMAS WILsoN, of Cleveland, in the county of (luyahoga and State of Ohio, have invented a new and Improved Convertible Anchor and Freight Hoisting Apparatus for Vessels, of which the following is a full, clear, and exact description.

Reference is to he had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a plan view of an anchor-hoist and capstan-engine, showing the connected freight-hoisting mechanism out of hangers, the capstanshnft being shown in section and the dcck-hatchway indicated in dotted lines.

Fig. 2 is a side elevation of the same and the capstan attached, showingthe upper and lower clerks in sectional elevation; and Fig. 3 is an end elevation without the capstan and showing the lower deck in section.

The invention will first be described in connection with the drawings, and then pointed out in the claim.

A represents a crank-shaft journaled in suitable hearings in the main frame A, mounted upon the base A which latter rests upon the lower deck, K. The shaft A is revolved by two engines, E E, and upon it is placed the sliding clutch B, which is adapted to engage and disengage the worm-wheel G on shaft G. Upon this shaft 0 is also secured the beveled gear'wheel J, which, through the beveled wheel J, imparts motion to the vertical capstanshaft L, which turns the capstan M, situated upon the upper deck, N. Upon the shaft G are also secured the chain pulleys or wheels 1? P, for operating the anchor chains.

To one end of the shaft A is secured the crank F, which is connected in this instance by the connecting-rod D to the crank F of the shalt G, held below the deck K in suitable hangers, Q. Parallel with theshaft G, and below, but in line with the hatchway R, is held in suitablepivoted hangers, H H, the hoistingdrum H, which is revolved from the shalt G by the friction-pulleys G G attached, respectively, to the shafts G and H.

When the drum H is to be operated, it is to be swung forward by the lever H", to bring the friction-pulley Gr into contact with the friction-pulley G. When the lever H is released the drum H and pulley G will swing away from the pulley G, and the shaft G revolve independently of the drum. By sliding the clutch B out of engagement with the worm wheel 0 the capstan mechanism will be th rowu out of action, and by simply sliding the clutch forward by the lever B, or otherwise, the said mechanism may be readily putin motion again.

Upon the shaft G is secured the balancewhecl E; but, in case other than a crank and connecting-rod connection between shaft A and shaft G be used, this may be omitted.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

An anchor and freight hoisting apparatus, comprising the capstan mechanism and anchorhoist, the shaft A thereof, the engines E, clutch B, connecting-rod D, and shaft G, arranged be tween decks,and the hoisting'drum H, arranged in line with the hatchways, substantially as described.
